What order should we follow for OCPI learning?

Start with OCPI basics, then terminology, then message flows and charging lifecycle, and finally hands-on simulator practice.

Who is this learning path for?

It is for engineering, QA, operations, and product teams involved in EV roaming integrations and support.

How do we turn learning into implementation quality?

Pair each module with scenario-based simulation and structured test runs so concepts are validated in practical workflows.

Recommended path

OCPI (Open Charge Point Interface) is the roaming protocol used by CPOs and eMSPs to exchange data such as locations, tokens, sessions, tariffs, and charge detail records. A clear mental model of the protocol reduces integration mistakes and speeds up debugging.

This guide is written to be practical: read the explanation, then validate your understanding with message-flow diagrams and hands-on simulations.

For a smooth learning progression, start with fundamentals, then move to terminology and message flows, and finally practice with the interactive simulator.
